What this page counts as Swanston
We could not find an openly licensed official boundary for Swanston, so this page uses a census-based area. For this page, Swanston means the 2010 Census block groups whose center lies within 1.6 km (1.0 miles) of the U.S. Geological Survey (GNIS) map point for Swanston (feature 1659934), each block group going to the nearest of the places we cover. Every number below is for exactly those block groups (listed in “How these numbers were made”), so the edges are approximate and may include or leave out a few blocks people would call Swanston.

Past claims do not predict future flooding, and a neighborhood figure cannot tell you about one building. Look up the exact address on the FEMA Flood Map Service Center and get flood insurance quotes before you sign a lease or a contract.

Flood zones street by street in Swanston
The named streets in Swanston, longest first, with how much of each street’s length inside Swanston lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Swanston; the main zone is the FEMA zone covering most of that length. A street can cross several zones, so the zone at one address can differ from the street’s main zone: check the address above for that. 33 shorter streets are not listed.

Flood zones in Swanston
Share of Swanston’s mapped area (about 4.567 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels. Effective date of the FIRM panel(s) covering it (06067C0177J, 06067C0180J, 06067C0181H): August 16, 2012, June 16, 2015.

| AE | 5.8% |
What the zones mean
- Zone AE (and A, AH, AO)
- High-risk: part of the Special Flood Hazard Area (SFHA), the area FEMA maps as having a 1-percent chance of flooding in any given year (the “100-year” or base flood). AE areas have a mapped base flood elevation.
- Zone VE (and V)
- High-risk coastal areas, also in the SFHA, where the base flood is expected to bring additional hazards from storm waves.
- Zone X (shaded)
- Moderate hazard: between the limits of the 1-percent and the 0.2-percent-annual-chance (“500-year”) flood.
- Zone X (unshaded)
- Minimal hazard: outside the SFHA and higher than the 0.2-percent-annual-chance flood elevation. Minimal is not zero: flood claims are filed from X zones too.

How much is flood insurance in Swanston?
The typical National Flood Insurance Program policy on single-family homes in Swanston costs $1,158 a year: the median of 17 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $838 and $1,317. That is the full amount paid for the year, the premium plus FEMA’s fees and surcharges, and every one of these policies is priced under Risk Rating 2.0. A quote for one building can be far from this: its elevation, foundation, age, coverage and deductible all change the price. Private flood insurance is not included.

Extreme heat in Swanston
FEMA’s National Risk Index rates heat wave risk for the census tracts that cover Swanston as: “Relatively Low” for 100% of the area. Their heat wave risk scores range from 31 to 46 out of 100 (national percentiles). The index weighs how often heat waves happen, what they are expected to cost, and how vulnerable and resilient the community is, so a dense area can rate differently from a nearby one (FEMA National Risk Index, Census Tracts feature layer, Version 1.20.0 (December 2025)).
Trees shade streets and buildings and cool the air around them (U.S. EPA: Using Trees and Vegetation to Reduce Heat Islands). In the USDA Forest Service’s 2025 satellite-based tree canopy map, trees cover about 5.3% of Swanston’s area on average, compared with 7.0% for Sacramento as a whole (the 20 Sacramento areas on this site combined) (USDA Forest Service. 2026. USFS NLCD Percent Tree Canopy CONUS v2025-6 (2025 map). Salt Lake City, UT).
During a heat advisory, follow the National Weather Service: Heat Safety guidance. Neighborhood averages cannot tell you how hot a particular home, block or unit gets.
Fire hazard severity zones in Swanston
California’s 2025 Fire Hazard Severity Zone maps do not place any of Swanston in a moderate, high or very high zone (CAL FIRE Office of the State Fire Marshal, Fire Hazard Severity Zones). Wildfire smoke and wind-blown embers can still reach areas outside the zones.

How these numbers were made
Area: the census-based definition above, using U.S. Census Bureau TIGERweb, 2010 Census Block Groups and U.S. Geological Survey, Geographic Names Information System (GNIS) domestic names. Flood zone shares: the area polygon intersected with FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, area computed in an equal-area projection; retrieved October 25, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Sacramento County (county code 06067), dataset as of September 8, 2026, retrieved October 25, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 060670069003, 060670055022, 060670063004, 060670055021, 060670054022. Neighboring pages can share a block group, so their counts can overlap. Paid totals add building, contents and Increased Cost of Compliance payments and are not adjusted for inflation; a claim whose FEMA record shows a negative payment (an adjustment) counts as zero. Tree canopy: the mean of the 2025 NLCD Tree Canopy Cover values (0–100%, 30 m cells in an equal-area projection) for cells whose center lies inside the polygon. Fire hazard severity zones: the 2025 zone polygons (Local and State Responsibility Areas) intersected with the neighborhood polygon in an equal-area projection; the share of area in each class. FEMA National Risk Index: census tracts intersected with the polygon in an equal-area projection; each rating’s share is the share of the polygon covered by tracts with that rating (tracts covering less than 1% are left out; together the tracts used cover 100%). We do not compute a new score. Tracts used: 06067005502 (48%), 06067005402 (34%), 06067006902 (11%), 06067006300 (6.6%). See the methodology.
